The Euarchontogwires cwade is based on DNA seqwence anawyses and retrotransposonmarkers dat combine de cwades Gwires (Rodentia + Lagomorpha) and Euarchonta (Scandentia + Primates + Dermoptera).[citation needed] So far, few if any anatomicaw features dat support Euarchontogwires have been recognized, nor does any strong evidence from anatomy support awternative hypodeses.

Euarchontogwires is now recognized as one of de four major subcwades widin de cwade Euderia (i.e., pwacentawia (pwacentaw mammaws)[1]), and it is usuawwy discussed widout a taxonomic rank but has been regarded as a cohort, magnorder, or superorder. Rewations among de four cohorts (Euarchontogwires, Xenardra, Laurasiaderia, Afroderia) and de identity of de pwacentaw root, remain controversiaw.[2]

One study based on DNA anawysis suggests dat Scandentia and Primates are sister cwades, but did not discuss de position of Dermoptera.[6] Awdough it is known dat Scandentia is one of de most basaw Euarchontogwire cwades, de exact phywogenetic position is not yet considered resowved, and it may be a sister of Gwires, Primatomorpha or Dermoptera or to aww oder Euarchontogwires.[7][8][9] Recent studies pwace Scandentia as sister of de Gwires, invawidating Euarchonta.[10][11]
